There is CQUAD4, PCOMP.
There is no RBE2/RBE3. But there is CRBE2/CRBE3. Are they the same?
No CBUSH found. You could use MYSTRAN. That program has CBUSH card.

The basic source code is there, free; the problem is there is not much more than that; it's basically just a collection of Fortran files, some test files, and a couple of manuals.

There are many solver options. The challenge is knowing which ones are still being developed, which have good documentation, strong user base, pre/post support options, open vs closed, etc.

very value informationnic wrote: ↑Fri Jul 17, 2020 3:27 pm Actually, Nastran's world is quite active. Three main "branches" co-exist (there are more of them, but those are the most widespread):
* MSC Nastranhttps://www.mscsoftware.com/fr/product/msc-nastran
* NX Nastran (siemens) https://www.plm.automation.siemens.com/ ... stran.html
* NEI Nastran (Autodesk)https://www.autodesk.com/products/nastran/overview
Femap (Siemens) and Patran (MSC) are the main legacy pre/post softwares for Nastran.
The trend is actually to integrate more and more the Nastran's solver in the core of CAD/PLM softwares such as the name of "nastran" can look more "hidden" than before.
One thing I really miss in other solvers I had the occasion to try is MPC constraints abstracted as 1D-like elements (cf. https://www.predictiveengineering.com/s ... -and-cbush)
